一般现在时的用法一、概述一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性，它不表示特定时间内发生的事。二、一般现在时的结构时态的结构指的是动词的变化形式。一般现在时间有两种结构，一种是动词原形，用于主语为非第三人称时的情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。Eg1.Weoftengetupearlyinthemorning.Eg2.Myfatheroftengetsupearlyinthemorning.三、谈谈“主语为三单，其后动词s添”在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单，其后动词s添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，如he,she,it,myfather,mymother,mysister,ourEnglishteacher,Tom,Mike,LiuJia,China,mybook,etc.Eg3.Hesometimesgoestoschoolbybike.Eg4.Myfatherworksinthehospitalasadoctor.四、动词第三人称单数变化规则动词第三人称变化的规则与可数名词复数变化的规则相同。规则一、一般在词尾加-s。如：looks,puts.reads,sees,skis等。规则二、以-o,-s,-x,-sh,-ch结尾的加-es。如：goes,does,misses,passes,mixes,fixes,pushes,wishes,watches,teaches,等。规则三、以辅音字母加y结尾的，变y为i，再加-es。注意一定是辅音字母加y才变，若是元音字母加y，则直接加-s。如：fly→flies,try→tries,fry→fries,copy→copiesbuy→buys,enjoy→enjoys,play→plays,say→says,pay→pays五、一般现在时的句子转换（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例：①陈述句：Sheisastudent.一般疑问句→Issheastudent?否定句→Sheisnotastudent.②陈述句：Icanswim.一般疑问句→Canyouswim?否定句→Icannotswim.（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do(you,以及复数),does（单数she,he,it）变成一般疑问句；在主语后谓语动词前加助动词don’t（I,you,以及复数),doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。例：①陈述句：Wegetupat7:00everymorning.一般疑问句→Doyougetupat7:00everymorning?否定句→Wedon’tgetupat7:00everymorning.②陈述句：Shehasalittlebrother.一般疑问句→Doesshehavealittlebrother?否定句→Shedoesn’thavealittlebrother.六、练习巩固1.写出下列动词的三单形式go__________catch_________brush（刷）_____wash___________do________like________have___________watch________drink___________fly___________say_______learn___________eat___________read___________sing___________buy__________study_______stay__________make__________look____pass__________carry____come__________plant(种植)______teach_______buy__________2.用括号内动词的适当形式填空。1.Weoften___________(play)intheplayground.2.He_________(get)upatsixo’clock.3.__________you_________(brush)yourteetheverymorning.4.What________(do)heusually______(do)afterschool?5.Danny_______(study)English,Chinese,Maths,ScienceandArtatschool.6.Mikesometimes__________(go)totheparkwithhissister.7.Ateightatnight,sheoften__________(watch)TVwithhisparents.8.________Mike________(read)Englisheveryday?9.Howmanylessons_________yourclassmate________(have)onMonday?10.Whattime_________hismother_________(do)thehousework?3.选择题()1.I________toschoolat7:00inthemorning.A.goB.goingC.goes()2.They_______bookseverydayinthelibrary.A.readsB.readC.reading()3.Themonkey________eatingbananasverymuch.A.likeB.likesC.liking()4.Myfather________toreadnewspaperaftersuppereveryday.A.likeB.likesC.liking()5.IlikewatchingTV,butmymother_________likeit.A.don’tB.doesn’tC.does()6.____________yourfatherdrinkmilkeveryday?A.doB.areC.does（）7.Wewillgoshoppingifit____tomorrow.A.don'trainB.didn'trainC.doesn'trainD.isn'train（）8.Hesaidthesun____intheeastand____inthewest.Arose;setBrises;setsCrises,setDrise;sets（）9.WangMei____musicandoften____tomusic.Alike;listenBlikes;listensClike;arelisteningDliking;listen（）10.Jenny____Englisheveryevening.AhasstudyBstudiesCstudyDstudied4.改错(划出错误的地方，将正确的写在横线上)1.IsyourbrotherspeakEnglish?__________________2.Doeshelikesgoingfishing?__________________3.Helikesplaygamesafterclass.__________________4.Mr.WuteachsusEnglish.__________________5.Shedon'tdoherhomeworkonSundays._________________5.把下列句子变成一般疑问句（并作肯定和否定回答）、否定句例：Ilikecooking.→Doyoulikecooking?Yes,Ido.No,Idon't.Idon'tlikecooking.1.Myfriendslikeplayingsoccer.2.TheyspeakEnglisheveryday.3.DanielwatchesTVeveryevening4.JohnisfromCanada.5.Tomdoeshishomeworkathome.6.Mydogrunsfast.7.Amylikesplayingcomputergames.8.Shecanplaythepianowell.
